These premium full aperture Thin Film Solar Filters allow only a safe amount of light to pass through your telescope, camera, and binoculars for solar viewing. It is an ND 5 filter, therefore blocking 99.999% of the Sun's visible light. The .002" thick black plastic polymer used for the filter substrate is a durable, high quality material that will last you for many years with proper care and handling. These filters are constructed with a single-layer design with absorptive filtering material spread throughout the substrate. Slight warps, bends, or wrinkles present in the film will NOT affect the solar image. The Sun appears in a natural looking yellowish-orange color that we are all familiar with, rather than harsh white-light.

This filter fits: Celestron: C4.5, C5/5i, FirstScope 114, NexStar 5/5SE, NexStar 114, 130GT; Meade: ETX 125, 114 EQ, DS-2114 ATS; Orion: ShortTube 4.5, SkyQuest XT4.5, 127 Mak.
